I'm 40 years old with a lovely and much-wanted 4 week old DD, who arrived after we had been trying for three years and had three miscarriages. She is actually a really good sleeper overall, both in the day and at night. She catnaps often but will usually have at least two longer naps in the day of between 1.5-3 hours, and at night she sleeps in stretches of 2-4 hours at a time, so I know I'm pretty lucky.
My issue is that I am finding it really difficult to relax when she is asleep. Except for between about 2am and 8am, when I think I'm so tired that if she is asleep I can drop off easily, it takes me ages to fall asleep at night. And when she naps during the day I find it hard to either relax or do anything useful because I am constantly on edge and listening in case she wakes up. It's quite draining and i feel anxious a lot of the time.
Is this normal? And how do I deal with it? I've tried talking to DH but he just said 'just try to relax, she's fine' which didn't really help
